ISL8002BIRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8002BIRZ-T7A is a monolithic synchronous step-down DC/DC converter manufactured by Renesas Electronics Corporation. It delivers up to 2A of continuous output current from an input supply ranging from 2.7V to 5.5V. The device operates at a fixed switching frequency of 2MHz, utilizing peak current mode control architecture for superior transient response and low duty cycle operation. Output voltage is adjustable from 600mV to the input voltage level. It features integrated PMOS high-side and NMOS low-side MOSFETs, eliminating the need for a bootstrap capacitor. The component is housed in an 8-lead TDFN package with an exposed thermal pad.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Review official product change notifications for any recent manufacturing updates. Ensure storage conditions meet specified humidity constraints to maintain device reliability during soldering processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator when a 2A output current capability and 2MHz switching frequency are required within a 2.7V to 5.5V input range. Consider the TDFN-EP-8 package for space-constrained designs needing improved thermal dissipation. Evaluate the need for external compensation versus internal options based on layout stability requirements. Compare against other ISL8002 variants if different switching frequencies or current ratings better suit the specific application load profile.
